ARCH SUPPORT.

Application :tiled April 2, 1925. Serial Nc. 20,050.

To all whom, t may concern Be it known that I, VILLIAM M. SCHOLL, a citizen of the Uni-ted States, and a resident of the city of Chicago, in the county of ICook and State of Illinois, have'invented y cel'taln new and useful Improvements 1n an Arch Support: and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to thc accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification. The invention relates to an improvement 1n arch supports for the longitudinal inner and transverse arch of the human foot.

` One of the objects of the invention is to improve devices of this character.

Another' object is to improve arch supports, of the character herein disclosed, wherein the arch-supporting plate is made relatively wider than that heretofore disclosed in my Patent No. 880,245 dated February 25th, 1908, to also extend' under the outer longitudinal arch of the foot to afford a larger area of support for the foot and in which the arch-plate -is made relatively shorter so as to not extend under the location of the oscalc-is of the foot.

Another object is to make the rear end of the leather coverplate of sufiicient length to extend rearwardly to lie fully and completely under4 the oscalcis of the foot,.to be formed into a rounded socket to receive the heel by the effect of the weight imposed thereon. the rear portion of the leather cover-plate heilig sufficiently wide to'contact the vertical wall ofthe heel of vthe shoe so as to not form sharp edges thereunder.

Another object is to cover the forward end of the spring-plate and ot' the archplate by a. relatively soft pad attached to theforcmost plate to prevent the end of the spring-plate from wearing into the underlying part of the shoe, said cushion being skived at its front end to prevent an abrupt shoulder, to the discomfort of the wearer, and which pad is placed withlits longest axis transverse to the plane containing the longitudinal arch and underlies the sesamoid and the metatarsal bones of the foot and affords them proper and suflcient supportV to maintain them in their normal natural position. y

Other objects, advantages and benefits will become readily 4 apparent to persons skilled 1n the art,

ation of the following description, when taken in Vconjunction with the drawings, wherein Figure l is a bottom plan View of .the arch support to be described herein.

Figure 4 is a transverse inverted section taken substantially on line IV-IV of Figure l.

In all the views the same reference characters are employedv to indicate similar parts.

silient metallic arch-plate, longitudinally curved or arched to conform substantially to the .longitudinal inner arch of the oot. A resilient metallic spring-plate underlies the 4arch-plate and is curved longitudinally on a radius longer than the radins upon which the arch-plate is curved, as clearly shown in the drawings. The sprlng-plate is secured to the arch-plate and to'the coverplate near the rear end of the twometallic plates` andat its front end the spring-plate entends forwardly `of the arch-plateand receives the front end of the arch-plate in.

sliding contact therewith. AA cover-plate of leather, or other suitable flexible materia-l and shaped to fit properly in the interior of the shoe and to be worn under the foot, covers both plates and is skivc'd to a thin edge at its front, and side, which latter is curved upwardly.

The rear end of the spring-plate does` not 1.60

extend rearwardly of the arch plateV and is not located at any time under the heel of` The device consists, in general, of a reis suiciently wide to underlie the metatar- I sals of the foot Vor to extend substantially coegttensive therewith. I prefer that the archpla-te be made of sufficient Width to underlie all of the metatarsal bones andthe cunei` iend than Vthe arch-plate, and to the front end of the spring-plate is attached a pad. 15`

skived into -a thin front edge 16. The pad 15 has its longest axis located in a plane substantially at rightangles to the longestl plane of the device and underlies the inetatarsal and the sesainoid bones of the foot. The cover plate, 17 of leather, is also'skived to a thin edge at its front enthas at 18, and together with the pad 15 which is normally in` Contact therewith, the front ends of the two metal, plates are enclosed. The pad 15 elevates the front end ot the device to. position to normally support the transverse or anterior nietatarsal arch, and at the same time it prevents the sharp end of the-spring-plate from contacting and rvcutting into the eX- posed surface of the shoe. The arch-plate is connected at its front end to the cover-y plate 17 by `a rivet extending through both plates, but the front end of the two underlying plates, 10 and 13, are not so connected together. The rear end 19 of the leather cover-plate 17 extends to the rear end of the shoe, as at 20, so that the heel of the foot of the wearer will produce -a curved socket, as shown at 21 more clearly in Figure 5. The rear ends 22 and 23 of the metal plates do not extend under the oscalcis of the f00t,.so that the cushion formed by the part 19 of the cover-plate is soft and yielding and the rear portion 19 of the cover-plate preventsI the device, as a whole, from working rearwardly when the wearer is using the arch support. The lpad is secured to the spring-plate 13 by rivets 23. l

The foregoing description, when taken in conjunction with my former patent to which reference has heretofore been made is a complete. disclosure of the present invention.

Having described my invention what I claim is new and desire to secure by Letters Patent is 1. An arch support comprisin a resilient n'ietal'spring plate sufficiently wi e to underlie the tarsal and meta-tarsal bones of the foot, said plate curved longitudinally throughout its length and curved outwardly and transversely at its inner edge near its longitudinal mid-portion, said plate terminating rearwardly in front of the tuberosity location of the oscalcis; a spring plate underlying said arch-plate, curved longitudinally on a longer radius than the radi-us of the longitudinal curve'of the arch-plate, said plates connected together at their rear ends; a pad connected to the front end of the spi'iiigplate for underlying the .metatarsal and sesainoid bones of the foot and -a {lexible covering f or said plates terminating near the front edge of'said pad and -at the rear boundary of the shoe heel, said pad and the front edge of said cover-plate enclosing the front ends of said arch-plate and spring-plate.

2. An arch support comprising a metal spring-plate for underlying the tarsal and metatarsal bones Ot the foot, said plate curved longitudinally throughout its length and curved transversely and upwardly near its mid-portion to support the inner longitudinal arch of the foot, said plate terminating rearwardly infront of the tuberosity location of the oscalcis; a spring-plate underlying said arch-plate curved longitudinally on a longer radius than the radius of the longitudinal curve of the arch plate, said springplate connected to the arch-plate in front of the latters rear end; a pad connected to the front end of the spring-plate having its longest axis in' a transverse plane and a leather cover-plate connected to thearch plate-and having its rear end of length to -rest in the heel seat of va shoe.
